Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an ammonia nitrogen wastewater treatment device. Background Technology

[0002] Ammonia nitrogen wastewater mainly originates from fertilizer, coking, petrochemical, pharmaceutical, food, and landfill industries. The discharge of large amounts of ammonia nitrogen wastewater into water bodies not only causes eutrophication and black and smelly water, but also increases the difficulty and cost of water treatment, and may even have toxic effects on humans and organisms. Before 2014, there were various treatment processes for ammonia nitrogen wastewater, including biological and physicochemical methods.

[0003] In existing technology, wastewater is fed into an ammonia-chlorine removal device, where the internal filtration system removes the ammonia and chlorine, thus achieving purification. However, in actual use, untreated wastewater contains impurities. Directly feeding wastewater into the ammonia-chlorine removal device can cause these impurities to accumulate inside, affecting the device's purification efficiency and potentially damaging the device. Summary of the Invention

[0004] The purpose of this invention is to provide an ammonia nitrogen wastewater treatment device.

[0005] The technical problem of this invention is mainly solved by the following technical solution: An ammonia nitrogen wastewater treatment device includes a tank I, a tank II located on one side of the tank I, a stirring mechanism located inside the tank II, a liquid inlet mechanism located at the top of the tank I, a drive mechanism located outside the tank I that can drive the liquid inlet mechanism to move back and forth and drive the stirring mechanism to rotate, and a rotatable filter mechanism located inside the tank I below the liquid inlet mechanism, the filter mechanism containing a cleaning mechanism. The filtration mechanism includes arc-shaped notches on both inner side walls of housing I, forming a circular structure between two sets of arc-shaped notches. An inclined plate extending into the corresponding arc-shaped notch is provided inside housing I. A communication port connecting housing II is provided on the side wall of housing I above the bottom of the inclined plate. A rotating shaft I driven by motor I is provided in the middle of the inclined plate.

A movable shaft rotatably connected to the baffle is provided at the end of the filter plate on the same side as the corresponding arc-shaped plate. An elastic element for fixing the other end of the filter plate is also provided between the two sets of baffles.

[0006] Preferably, the cleaning mechanism includes water storage cavities disposed at both ends of the inclined plate and extending into its side walls. Both ends of the inclined plate are provided with spray holes communicating with the corresponding water storage cavities. The upper water storage cavity opening is connected to the connecting port. A flat water inlet pipe is provided on the outside of the box body I, with one end extending into the lower water storage cavity opening. The water inlet pipe is driven by an electric push rod I.

[0007] Preferably, the side wall of the housing I is provided with an installation opening for the water inlet pipe to pass through, and a connecting pipe is provided on the top of the water inlet pipe on the outside of the housing I.

[0008] Preferably, the elastic element is located between the inclined plate and the corresponding filter plate. The elastic element includes a support rod mounted between the two sets of corresponding baffles. The support rod is provided with a V-shaped elastic sheet connected to the end of the corresponding filter plate. The support rod and the corresponding filter plate are also connected by a taut connecting rope.

[0009] Preferably, an electric push rod II is inclined upward on the outer side of the housing I and located below the filter mechanism, and the electric push rod II is located on the same side as the top of the inclined plate.

Slides passing through the sliding openings are also provided at both ends of the spray pipe. The stirring mechanism includes multiple sets of mounting rods arranged laterally inside the housing II. The two ends of the mounting rods are fixedly connected to the side wall of the housing II via bearings. Stirring paddles are evenly distributed on the mounting rods. The multiple sets of mounting rods form a V-shaped structure, and sprockets I are correspondingly provided on the multiple sets of mounting rods. The driving mechanism includes lead screws located on the front and rear sides of the housing I. The two ends of the lead screws are fixed by bosses. The lead screws pass through screw holes in the corresponding slides. One set of lead screws is driven by a motor II. A sprocket II is also provided at one end of the lead screw.

Detailed Implementation

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] An ammonia nitrogen wastewater treatment device includes a housing I1, a housing II2 located on one side of the housing I1, a stirring mechanism 3 located inside the housing II2, a liquid inlet mechanism 4 located at the top of the housing I1, a drive mechanism 5 located outside the housing I1 that can drive the liquid inlet mechanism 4 to move back and forth and drive the stirring mechanism 3 to rotate, a rotatable filter mechanism 6 located inside the housing I1 below the liquid inlet mechanism 4, and a cleaning mechanism 7 located in the filter mechanism 6. The filter mechanism 6 includes arc-shaped notches 61 on both sides of the inner wall of the housing I1. The two sets of arc-shaped notches 61 form a circular structure. An inclined plate 62 extending into the corresponding arc-shaped notch 61 is provided inside the housing I1. A communication port 63 communicating with the housing II2 is provided on the side wall of the housing I1 above the bottom end of the inclined plate 62. A rotating shaft I64 driven by a motor I65 is provided in the middle of the inclined plate 62. Arc-shaped plates 66 that are attached to the side wall of the corresponding arc-shaped notch 61 are provided at the top and bottom of the inclined plate 62. Baffles 67 that are attached to the inner wall of the housing I1 are provided on the front and back sides of the upper and lower ends of the inclined plate 62. A filter plate 68 is provided between the two sets of baffles 67. The filter plate 68 on the same side as the corresponding arc-shaped plate 67 has a movable shaft 69 that is rotatably connected to the baffle 67 at its end. An elastic element 610 for fixing the other end of the filter plate 68 is also provided between the two sets of baffles 67.

[0017] The elastic element 610 is located between the inclined plate 62 and the corresponding filter plate 68. The elastic element 610 includes a support rod 6101 mounted between the two sets of corresponding baffles 67. The support rod 6101 is provided with a V-shaped elastic sheet 6102 connected to the end of the corresponding filter plate 68. The support rod 6101 and the corresponding filter plate 68 are also connected by a taut connecting rope 6103.

[0018] The cleaning mechanism 7 includes water storage chambers 71 disposed at both ends of the inclined plate 62 and extending into its side walls. Both ends of the inclined plate 62 are provided with spray holes 72 that communicate with the corresponding water storage chambers 71. The opening of the upper water storage chamber 71 is connected to the connecting port 63. A flat water inlet pipe 73 is provided on the outside of the box body I1, extending into the opening of the lower water storage chamber 71. The water inlet pipe 73 is driven by an electric push rod I74. An installation opening for the water inlet pipe 73 to pass through is provided on the side wall of the box body I1. A connecting pipe is provided at the top of the water inlet pipe 73 on the outside of the box body I1.

[0019] like Figure 2 As shown, an electric push rod II8 is installed on the outer side of the housing I1 at an angle upwards, located below the filter mechanism 6. The electric push rod II8 is installed on the same side as the top of the inclined plate 62.

[0020] The liquid inlet mechanism 4 includes a sliding opening 41 located on the top of the front and rear side walls of the housing I1. A spray pipe 42 is installed inside the housing I1. Spray nozzles are evenly arranged at the bottom of the spray pipe 42. An installation pipe is installed at the top of the spray pipe 42. Slide seats 43 passing through the sliding opening 41 are also provided at both ends of the spray pipe 42.

[0021] The stirring mechanism 3 includes multiple sets of mounting rods 31 arranged horizontally inside the housing II2. The two ends of the mounting rods 31 are fixedly connected to the side wall of the housing II2 through bearings. Stirring paddles 32 are evenly arranged on the mounting rods 31. The multiple sets of mounting rods 31 form a V-shaped structure, and sprockets I33 are correspondingly arranged on the multiple sets of mounting rods 31.

[0022] The drive mechanism 5 includes lead screws 51 located on the front and rear sides of the housing I1, wherein the two ends of the lead screws 51 are fixed by the bosses, and the lead screws 51 pass through the screw holes in the corresponding slides 43. One set of lead screws 51 is driven by a motor II52. One end of the lead screws 51 is also provided with a sprocket II53. The two sets of sprockets II53 are connected to multiple sets of sprockets I33 by a transmission chain 54 that passes through the mounting opening on the top wall of the housing II2.

[0023] like Figure 2 , 4 As shown, a sealing plate 9 is provided inside the communication port 63 to seal it, and a rotating shaft II10 is provided on the top of the sealing plate 9 to be rotatably connected to the side wall of the communication port 63.

[0024] like Figure 2 , 3 As shown in Figure 4, wastewater is injected into the spray pipe 42 during use. The motor II 52 drives the lead screw 51 to rotate in the screw hole in the slide 43. This drives the slide 43 to move back and forth in the sliding opening 41, while simultaneously moving the spray pipe 42 above the filter mechanism 6. This allows the liquid sprayed from the nozzle in the spray pipe 42 to cover different areas on the top of the filter plate 68, preventing a large amount of liquid from being sprayed onto the fixed area on the top of the filter plate 68 for a long time, which would cause a large accumulation of impurities in that area and affect the subsequent filtration effect and efficiency.

[0025] Meanwhile, the liquid sprayed on the upper filter plate 68 flows into the top of the inclined plate 62 below after being filtered by it. Then, it flows along the inclined surface of the top of the inclined plate 62 to the connecting port 63. Alternatively, some of the liquid flows into the upper water storage chamber 71 through the upper spray hole 72 and flows along its inclined surface to the connecting port 63. At this time, the impact force of the liquid pushes the sealing plate 9 to rotate counterclockwise in the connecting port 63 with the rotating shaft II10 as the center. This opens the connecting port 63 and allows the liquid to flow into the box II2. When the screw 51 rotates, it drives the sprocket I33 to rotate through the sprocket II53 and the transmission chain 54. The sprocket I33 drives the mounting rod 31 and the stirring paddle 32 to rotate, causing the stirring paddle 32 to agitate the filtered liquid in the box II2, so that it mixes with the lime water additive in the box II2 and reacts to form an insoluble precipitate.

[0026] In the above process, the rotating shaft I64 supports and fixes the middle of the filter mechanism 6. The water inlet pipe 73 is inserted into the water storage chamber 71 to fix one end of the filter mechanism 6, preventing the filter mechanism 6 from rotating around the rotating shaft I64, thereby improving its stability.

[0027] When the upper filter plate 68 needs cleaning after prolonged filtration, the drive mechanism 5 drives the spray pipe 42 to move to the top side inside the housing I1 and stops working. At this time, the electric push rod I74 drives the water inlet pipe 73 to move to the left and pull it out of the water storage chamber 71 to prevent it from affecting the rotation of the filter mechanism 6 around the rotating shaft I64. Then, the motor I65 drives the rotating shaft I64 to drive the inclined plate 62 to rotate 180 degrees clockwise inside the housing I1, so that the filter plate 68 with accumulated filter material rotates to the lower part of the filter mechanism 6, while the filter plate 68 in the clean state rotates to the upper part of the filter mechanism 6. When the filter mechanism 6 rotates, without the liquid impact sealing plate 9 above the inclined plate 62, it is in a vertical state under the influence of the weight of the sealing plate 9 itself and seals the connecting port 63, preventing the filter material on the upper filter plate 68 from flowing into the connecting port 63 and into the housing II2 when the filter mechanism 6 rotates.

[0028] When the filter mechanism 6 is flipped, the electric push rod I74 drives the water inlet pipe 73 to insert into the liquid storage chamber 71 below. At this time, the liquid inlet mechanism 4 can work to spray liquid onto the filter plate 68 above and perform normal filtration. At the same time, the electric push rod II8 works, and its output shaft frequently contacts and separates from the left end of the filter plate 68 below, thereby squeezing the filter plate 68 below so that it rotates clockwise around the right rotating shaft II69 and compresses the V-shaped elastic sheet 6102 below. When the output shaft of the electric push rod II8 separates from the filter plate 68, the V-shaped elastic sheet 6102 expands and pushes the filter plate 68 below to rotate counterclockwise around the right rotating shaft II69 and return to its original position. This shaking motion causes the lower filter plate 68 to vibrate, dislodging impurities adhering to its end face and depositing them at the bottom of the housing I1, thus cleaning the impurities. Similarly, when liquid is introduced through the liquid inlet mechanism 4, the liquid rinsing the upper filter plate 68 also vibrates it, preventing impurities from clogging it and improving the filtration effect and efficiency. While separating impurities from the lower filter plate 68 by shaking it, the cleaning liquid can also be drawn into the water inlet pipe 73 and flow into the lower liquid storage chamber 71, and then sprayed out through the corresponding water spray holes 72 to rinse and clean the lower filter plate 68, thereby improving the cleaning efficiency and effect of the impurities on the lower filter plate 68.

[0029] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
